That looked like a fun paddle! I’m glad everything is coming together.

That’s the solution I proposed in my previous post, but that’s what I’m saying – if you split this into two pieces you might as well carry the adapter that came with the pump, which will be lighter in total

I see this, but the tightness of the fit should already work for hands free operation. I based the dimensions off the flextail adapter for Boston valves, which is the one with the the little rubber attachment – if you pull that off you’ll find that the little plastic piece left over fits perfectly onto the valve.

I’m still building my packraft -…[Read more]

Hey Krafter, have you seen the screw-on adapter shown here? Merging your design with the Boston Valve screw-on on threads would allow hands-free operation.

I was initially thinking about trying to figure this out, but I was a little DIYed out and just bought one from MRS. Not sure how well it’ll work, but I’ll report back. I’ve found almost all of my leaks and fixed them but I’m still finding I need about 5-10 breaths per hour. If something like this ends up on the store, I bet it’d be pretty…[Read more]

Here is one of my modified spray skirts, as requested.

(Above) Front profile.

(Above) Rear profile.

I had an issue where my more forward seating position made the spray skirt too tight around the waist. To address this, the torso funnel was cut off and four additional 150GSM fabric panels were cut from the fill…[Read more]

I think the solution might have been staring us in the face.

Why not maintain your original design, but add an adapter designed to slot over your existing one? We could then cut out an adapter attachment similar to what the Boston valve uses.

If designed with a lip, you’d just need to epoxy one ring to each adapter.

This would have the added…[Read more]

The windows aren’t the real problem – you can close them with your fingers in a pinch.

The problem is that the pins on the end don’t allow for a mating with the other valve. The location of the holes in the Boston valve determine the inner and outer diameter of the adapter. It’s too big to fit inside the other valve and too small to fit…[Read more]

It was. Class 2 and nothing catastrophic. I did rip the hole that held my seat in place to the floor. Seat is fine, but I’ll need to rig something to hold it in place. Have a slow leak that I need to work on. I had added bail holes near the seat but need to add a lot more based on my water test. I posted one of my laps on the Facebook page. I…[Read more]

Great solution! I hope the first float was a success.

Yes, adding some fabric things like a rolled-up sleeping mat seems to create a kind of surface that conforms to your feet fairly well once the air is pushed out through the valve.

The pumps are easily worth it. It’s so much better than inflating a boat manually. Plus they are great for filling air mattresses, inflatable life jackets, and helping campfires. I’m honestly surprised they aren’t just standard kit with these boats.

Yes, the valve used for the seat.

It would be interesting if your design could be modified in a way that would be workable for both the Boston Valve and these seat valves.

Carrying multiple adapters isn’t practical when using these boats for something like portage backpacking. Too easy to lose small accessories.

I bet a similar design without…[Read more]

Are you talking about the backrest/seat tube-style valves or the little red tab-open valves that you see on camping pillows?

This doesn’t work with the tube-style valves because the pins get in the way; I haven’t tried the other ones, but I suspect it might work if you don’t mind where the pins end up on the other side. The one caveat is that the…[Read more]

You maybe could add some sort of foam balls or something like that to inflate and then deflate so that they conform to your foot spot. I’ve got Jackson happy feet in my ww kayak with this. Most have mixed feelings about it, but I love the way it conforms to my feet in my kayak.
